PHILIP A. MYERS, OF ASHLAND, OHIO, ASSIGNOR OF ONE-HALF TO FRANCIS E. MYERS, OF SAME PLACE.

DEEP=VVELL PUMP.

SPECIFICATION forming part of Letters Patent No. 384,585, dated June 12, 1888. Application filed January Q8, 1888. Serial No. 262,244. (No model.)

To all whom it may concern;

Be it known that I, PHILIP A. MYERS, of Ashland, in the county of Ashland and State of Ohio, have invented a new and useful Improvement in Deep-Vell Pumps; and I do hereby declare that the following is a full, clear, and exact description of the same.

Heretofore in the construction of pumps in which a submerged or forcing cylinder has been used it has been necessary to provide an csoapevent for the accumulation of water which gathers above the piston working in the submerged cylinder. Such escape-vents have invariably been arranged in the head of the submerged cylinder, and have extended through the main barrel of the pump, so as to discharge the accumulated wat-er into the well,

It is the object of my invention to overcome the diiculties which are present in the constructions referred to, and which are objectionable for the reason that this leakage (which in some cases is considerable) is wasted as it iiows back into the well. Further, in bored wells,where the well-opening is ofsmall diameter,the water thus discharged has a washing effect, and is liable to displace the earth on the outside of the main pump-barrel.

By the use of my invent-ion Iobviate the objections above referred to, as I allow for the discharge of the accumulated water directly into the main discharge-pipe of the p`ump,thus saving all leakage and waste, as the water is carried up with the main column and discharged.

My invention also includes means for preventing the entrance of the water from the dis-` charge-passage ofthe pump into the submerged cylinder above the piston therein; and, further, it includes an improved attachment of the pump barrel and cylinder with the pumpstock. Y

In the accompanying drawings I have illustrated my invention as applied to a deep-well pump, such as is ordinarily used in bored wells; 45 but I desire it to be understood that I have simply shown the invention in this connection for convenience, and that the invention may be applied to any pump in which a submerged cylinder is used. 5o Figurelrepresents avert-ical central section through the pumpstock, the main barrel, and the submerged cylinder, the lower bucket of the pump being omitted. Fig. 2 is a section of the pump-stock, taken on the line :v a: of Fig.

I, the connection between the stock and the :5 main barrel being shown in elevation. Fig. 3 is aplan view of the submerged cylindenshowing the valve lifted.

In the figures, a represents the pump-stock, which is formed as an air-chamber, preferably 6o oblong in cross-section. Cast upon the top of the stock is a standard, b, which serves as a support for the pump-handle c. Attached to this handle isa piston-rod, d, which passes down through a guide-pipe, e. This piston- 6: rod carries the ordinary pistons, asf, as will u hereinafter be more fully described.

In the class of pumps shown an opening is made in the ground by driving or drilling, and in this opening atwo or twoand-a-half inch 70 pipe is inserted,tting closely the opening. This pipe is shown in thetigures at A. It is of uniform diameter, and in the present case, after it is driven into the ground, Iconnect the pump-stock in the following mannerz' The 75 pump-stock has a lower iiange, h, to which is connected an annular ange or ring, fi, by means of bolts, which are secured to the ring land pass up through openings in the flange h, being screw-th readed upon their upper ends 8o to receive nuts, thus securing the two parts together.

rIhe bottom of the air-chamber within the pump-stock inclines toward the center, so as to allow of the complete drainage ofthe water S5 from this chamber. The discharge-spout k extends down to near the bottom within this chamber, and the discharge of this water is aided and made regular by the reaction of the air after it has been compressed by the infiow- 9o ing water. The flange i has a projection, Z, upon its under surface, screw-threaded on its interior periphery, and this rests upon and is screwed to the upper screw-threaded end of the main barrel A. In this manner the pump-A 95 stock is supported. The guide-pipe for the piston-rod is screwed into the top plate ofthe pumpstock, passing down through the air chamber into the main barrel, where it sup` ports the submerged cylinder B. The -upper roo end of the llange part t is recessed to form a seat, and in this recess is seated a reducingcollar, n, with a leather packing-ring, n, bcneath the same. The collar u is internally screw-threaded, and a short section of pipe, mi, connects the collar with a screw-threaded opening in the pump-stock.

The piston-rod, from the point where it is shown as broken ofi', extends down into the well or barrel,with alift-bucket upon ilslower end, a section of the ordinary wooden actuating-rod used in this class of pumps being shown ato. As this part of the pump is of ordinary and well-known construction,I have not considered it necessary to show it. The head of the submerged cylinder I perforate, as shown at p, and above these perforations I place a disk of leather or other suitable material, q, the disk being held in position by means of a jamnut, s. It will thus be seen that in the movement of the piston within the submerged cylinder any water which may have accumulated above the same will be forced out through the perforations i n the head, the leather disk allowing ofthe free passage of the water. The water thus discharged is carried along with the main column of water to the discharge-spout withoutany waste whatever. Thc weight of the water above the submerged cylinder tends to keep the leather disk over the perforations in the head, and thus prevents the entrance of the water from the main column into the submerged cylinder above its piston.

It will be understood that instead of the form of valve shown any suitable means may be used to allow of the exit of the water into the main discharge which will at the same time prevcntthe return of the same.

I arrange the main barrel with a vent, r, at or near the level of the submerged cylinderA head, and this keeps the pipes above that line free from water at rest, as after the action of the pump ceases this water will fiow backinto the well. By reason of the communication between the interior of the submerged cylinder and guide-pipe with the outer water-space, the water in the guide-pipe is always kept at the same level as the water outside in the outer chamber, and is always kept free from the accumulation of water-that is, if, after the action of the pump ceases,water remains in the barrel and guide-pipe above the line of the frost-vent, the water in the barrel will iiow out through the vent down to this point, and as the column of water in the barrel lowers the column ofwater in the guide-pipe will lift the valve over the.openings in the cylinderhead, and in this way the two columns will keep the same level until the guide-pipe is entirely emptied.

I am aware that prior to my invention means have been provided to allow for the exit of water from above the piston of the inner or smaller cylinder by passages formed through the piston, with a valve covering the passages when the piston is in action, and, as I have before stated, in pumps of the class to which my invention belongs it has been customary to provide for the leakage past the piston of the submerged cylinder by extending a discharge-passage from the space above the piston to the outside of the pump, and I do not, therefore, broadly claim an exit for the water above the piston in the submerged cylinder.

Having thus described my invention, what I claim isl. In a pump, the combination, with the main barrel forming a passage for the column of water in its upward movement to the point ofdischarge,and adischarge-pipe in connection with the upper end thereof, ol' a submerged cylinder within the same provided with apiston, and an opening in said submerged cylinder into the barrel above its piston, whereby the water which accumulates above the piston ofthe submerged cylinder is discharged directly into the column of discharging water, substantially as described.

2. The combination, in a pump, of a main barrel forming a dischargepassage to the surface and in connection at its upper end with the discharge, a cylinder` within the same, a piston-rod and pistons, and a valved opening in the submerged cylinder between the cylinder and the main barrel, substantially as described.

3. A pump consisting of a main barrel forming a discharge-passage to the surface, a submerged cylinderwithin the same, a pistonrod carrying pistons of unequal diameter, a guide-pipe for the piston-rod connected to and supporting the submerged cylinder, and val ved openings to the main discharge in the head of the submerged cylinder, substantially as described.

4. A pump consisting of a pump-stock, a main barrel, a submerged cylinder within thc barrel, and a piston-rod and piston, combined with a iange, 7L, on the pumpstock, a llanged ring, t', suspended from the iiange h, a collar, n, seated in a recess in the upper part of the ring i, and apipe, naconnecting the stock and collar n, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
